[R-SIG-Finance] RBloomberg (java version) error

[Ana Nelson]

Hi, Nacho,

Please try the following and let me know how they work.

1) Connect just as

cn <- blpConnect()

2) Do you have a file called blpapi3.jar in C:\Program Files\blp\API
or its subdirectories? If so what is the exact path to this file.

3) Can you upgrade to the most recent version of the Bloomberg API
(probably need to ask your IT department if you don't have admin
rights)
